ドローラポスト組立体。[Claims for Utility Model Registration] (1) A shaft installed upright on a base, upper and lower flanges fitted vertically at intervals between the upper and lower ends of the shaft, and A guide roller of a VTR or the like, which is equipped with a roller body rotatably fitted between the upper and lower flanges, and is disposed on the tape inlet side and outlet side of a rotating drum to regulate the vertical position of the tape when the magnetic tape is running. In the post assembly, a ring-shaped member made of a metal material with a high specific gravity is integrally provided on the roller body on either the tape inlet side or the tape outlet side, and the ring-shaped member is provided with a guide portion for regulating tape running. A guide roller post assembly characterized in that it is provided with a guide roller post assembly. (2) A ring-shaped member made of a metal material with high specific gravity is provided on the roller body on the tape inlet side, and the inertial mass of the roller body is transferred to the I.L. P
(Impedance) The guide roller post assembly according to claim 1, wherein the guide roller post assembly is set to have a moment of inertia equal to or greater than that of the roller. (3) The guide roller post assembly according to claim (1), wherein ring-shaped members made of a metal material with high specific gravity are integrally provided on the roller bodies on the tape inlet side and the tape outlet side.
